ICE-CREAM FREEZER.

SPECXFICATION forming part of Letters Patent No. 720,856, dated February17, 1903.

Application filed August 8, 1902 Serial No. 118,860. (No model.)

ful Improvement in loe-Cream Freezers, ofV

which improvement the following is a specication.

My invention relates to ice-cream freezers. The objects of my inventionare, rst, to

produce a device the-receptacle to contain' the freezing mixture ofwhich is provided with a removable'cover; second,to provide a knife orscraper adapted to remove the cream from the inner surface of thecream-receptacle without abrading or removing any of the tinningtherewith, and, thirdly, to provide in such types of machines a combinedwhipper and agitator; and to accomplish these several objects myinvention consists in the novel combination and arrangement of partshereinafter more specifically described, reference being had to theaccompanying drawings, forming part hereof, in which like referencecharacters indicate like parts wherever they occur, and in which- Figurel indicates a longitudinal section of my improved freezer. Fig. Zis atransverse section of the same, and Fig. 3 is a detail of thecream-receptacle and hollow shaft.

Referring to said drawings, l indicates an exterior cylinder forming thereceptacle to contain the congealing or freezing mixture. The saidcylinder is provided with an apertured cap or cover ci, adapted to besecured to the body of the cylinder at @c by the wire clamp h, by bolts,or in any other suitable manner. At the point where said cap engages thebody of said cylinder' a rubber gasket c is interposed to produce awater-tight joint. This cap a is removable to enable easy access to behad to the interior of the receptacle for the purpose of charging thefreezing mixture therein, cleaning out said receptacle, or for any otherdesirable purpose. The end of said cap is provided with acentrally-disposed aperture d, through whichone end of thecream-receiving receptacle 2 projects, and the end of the body portionof said cylinder 1 opposite thereto is provided with an aperture e, inwhich one end of the hollow shaft 3 projects andis secured upon theadjustably-disposed end of the bracket 4, nuts f g and gaskets h and ilserving to form a watertight joint at such points. The outer enlargedend j of shaft 5 is secured to the adjustably-disposed end of thebracket Ll, which .is adaptedl to be adjusted to any angle desired andheld in such position by means of asetscrew k, the opposite end'of saidshaft 5 being seated in the bearing l, formed in the member 6.

A hollow roll 8, mounted on one member of the U -shaped shaft 9, islocated in the interior cylinder or cream-receptacle 2 on one side ofthe hollow shaft. The said roll 8 is provided with series of slits m m,which serve as agitators or whippers upon the cream during the rotationof the roll and the interior and exterior cylinders, the said roll beingfrictionally driven by impact with the inner surface of thecream-receptacle in the same direction to the rotation of the cylinderin which it is mounted. During the rotation of said cylinders and rollthe cream contained in the 'interiorcylinder is uniformly acted upon bythe roll and is pasted or'impressed thereby upon the interior surface ofthe cream-receptacle and thoroughly frozen thereon and is then removedtherefrom by the blade or knife 10, which coincides in length with thecream-receptacle and is secured therein in such manner that the edge ofthe blade is in contact with the inner surface of saidcream-receplLacie. The said knife is preferably formed of any suitablehard wood or of a blade formed of hard Wood inserted or carried by ametal support, the action of the Wood upon the metal sides of thecreamreceptacle largely preventing the danger of abrading the same orremoving any part of the tinning in scraping off the cream. A series ofbrace-clamps l1 are secured in the cream-receptacle, one end of the sameencircling the hollow shaft and such brace-rods serving to act oroperate as whippers during the freezing operation. As the cream isscraped off the sides of the creamreceptacle it drops into the bottomthereof, from which it may be readily dipped or removed by removing thelid l2vv of the creamreceptacle.

The apparatus may be secured to a table or other support by the clamp13.

Having described my invention, what I IOO claim, and desire to secure byLetters Patent, 1s

1. In an ice-cream freezer, the combination of an exterior receptacle tocontain the freezing mixture rotatably mounted on a shaft and having aremovable top, a cream-receptacle mounted on the same shaft-as saidexterior receptacle, and adapted to rotate therewith, a hollowfriotionally-driven roll mounted in the interior of said creamreceptacle and means to secure the removable cap of said exteriorcylinder.

2. In an icecream freezer, the combination of an exterior cylinderadapted to contain the freezing mixture and rotatably mounted upon ashaft and having a removable top the said exterior cylinder beingsecured upon an` ad- SAMUEL SWEENEY.
